Lizard Leg

I've heard that the dry suits have silicon seals at the wrists, neck and ankles. My prosthetic (below knee, right) uses a suction system of attachment. A 3mm silicon liner rolls on against my skin and stays attached by friction. My leg goes inside of the carbon fiber socket, and then a 3mm thick silicon sleeve rolls up. This sleeve creates an airtight seal around the socket and against my skin above the internal liner.
So - skin,silicon liner, carbon fiber socket, silicon sleeve creating an airtight seal and a one way air valve expulsing the air, and not letting it back in.
On land, you could rip my leg out of socket before it let go. Underwater, I can get about 45-60 minutes before the water has worked its way under the outside silicon sleeve and then under the inside silicon liner - once this happens, no friction grip, no seal, more water pours in and everything starts sliding off.
I was wondering if any of the dry suit divers might have a suggestion as to how to get this to seal better against my skin?
